This is the killer Zed feature, IMO, that they support almost any agent via extensions. I deleted Cursor but still use the agent via Zed because it’s a lot nicer experience, Zed never had popups telling me Grok is half off. I also use OpenRouter and Zed.dev with it, that’s three providers out of dozens that it supports.

Exactly. The more competitive the space is, the more important it is that products purposefully support 3rd-party providers. Now that people are increasingly switching from Anthropic/OpenAI for inference reseellers and on-prem compute, transparency and portability will be the new values, not being slightly better than the next agent or model.
